    Going to try loading 410 with published Alliant recipe using 300 MP

    Problem is neither MEC nor Alliant list 300 MP on their bushing charts.

    Recipe calls for 16.4 grains, anyone know for sure which bushing to try. Obviously I'll be weighing and fine tuneing bushing, but just looking where to start to make sure I have the bushing available.

    Thanks

    Contac Alliant and they should help you with the load. I use Alliant 410 powder and use a #12 bushing for 11.9 grains, Maybe MEC has a size for the Powder?

    You can start with several bushings and see what throws the best. Also check your drop for shot, I had to make the bushing bigger because the shot was light on the 1/2 ounce bushing I had. The bushings usually throw lighter charges than the markings.

    My bushing that throws 16.0 gr. of H110/296 also throws 16.0 gr. of the 300MP. Ron
